This Planet's Death Spiral Could Teach Us A Lesson About Rocky Exoplanets
Reported by Universe Today
Macquarie University astronomers have tracked an extreme planet's orbital decay, confirming it is spiraling toward its star in a cosmic death dance that could end in three possible ways. It could cross the Roche line and be torn apart, it could plunge to d...

The Habitable Worlds Observatory Could Find More Very Massive Stars
Reported by Universe Today
Very massive stars (VMSs)have had a massive impact on the formation of our universe. However, there aren’t very many of them, with only around 20 known specimens in the Milky Way and Large Magellanic Cloud. Even observing those is difficult for the curre...

Synthetic Biology Could Support Future Outposts on the Moon and Mars
Reported by Universe Today
When we leave Earth, we have to bring everything with us, from the air we breathe to the food we eat. For example, a 6-person, 1000-day mission might require 108 tonnes of food. In a new paper, researchers suggest ways that synthetic biology could allow us...

Astronomers Use the Colours of Trans-Neptunian Objects' to Track an Ancient Stellar Flyby
Reported by Universe Today
Trans-Neptunian Objects reside in the distant Solar System as remnants of the System's early days. They follow unusual orbits and range in colour from reds to greys. New research uses their colours and orbits to show how a stellar flyby can account for the...

To Find Another Earth, We Need to Understand Atmospheric Escape
Reported by Universe Today
Atmospheric escape shapes an exoplanet's future. Earth's exosphere is extended and detectable due to ocean-related atmospheric escape. If we can detect the same features on an exoplanet, it could suggest oceans and habitability. But we need to build the Ha...
